The producers pick the best snippets of the flick, the ones that put the movies' best foot forward while providing an overview of the storyline, and hope the teaser does just enough to intrigue the viewer to spend their hard earned cash.

There's nothing wrong with being excited about a team you've followed during training camp. But a good trailer, or a sensational training camp practice doesn't guarantee you the movie, or the team won't flop when finally released.

We've all been there.

The Miami Dolphins have done a good job piquing my interest so far, creating some intrigue about the coming attraction (the exhibition season, then the 2014 regular season).

Everyone who cares about the Dolphins knows Ryan Tannehill's development in this new offense is the key to Miami turning in a winning franchise and so far the Dolphins' starting quarterback is off to a good start.

It has only been three practices, but Tannehill is making noticeable progress in his areas of weakness.

Tannehill is getting the ball out of his hands quicker, and he's connecting on deep passes. He's delivered at least one big play during 7-on-7s or 11-on-11s in all three of the team's practices.

That's a significant improvement considering Tannehill would go weeks without a deep ball connection during his previous two training camps.

But he's not the only offensive starter who seems to be blossoming. Tailback Lamar Miller is bigger, stronger, and seems to be a better fit for this spread offense.

He studied film and worked out with 49ers standout Frank Gore this offseason, and has been advised about this offense from LeSean McCoy, who used it to blossom into the NFL's most productive tailback last season in Philadelphia.

When the action becomes live we'll learn if Miller's progression is for real, or if this former University of Miami standout is really fool's gold. He'll have at least the first two or three exhibition games to impress while Knowshon Moreno works his way back from a knee injury he had scoped last month.

But it won't matter who the Dolphins have at tailback if the new offensive line can't create more running lanes than last year's unit.

However, Daryn Colledge looks legitimate based on what he's shown in the first few practices, despite not being signed until after Miami's minicamp.

Colledge, a eight-year veteran who has started 124 NFL games, is the only interior lineman that gives defensive tackle Randy Starks trouble. That means he passes the sniff test.

The Dolphins need to find two more starters to put between left tackle Branden Albert and right tackle Ja'Wuan James until Pro Bowl center Mike Pouncey is cleared to practice, which likely won't be any time soon considering he's not even running on his surgically repaired hip yet.

There are valid reasons to be encouraged about the 2014 Dolphins' progress, like the progress we've seen from Tannehill and Miller, the flashes of playmaking ability rookie receiver Jarvis Landry has shown, Charles Clay's continued development and the talent level of Miami's defensive linemen.

However, there are also genuine issues that still must be addressed before coach Joe Philbin's team is ready to be declared playoff worthy.

The linebacker issues remain, even with Koa Misi moving to the inside linebacker spot. This unit still needs to prove they can do a better job containing the run and covering tight ends and scatbacks.

Miami's still searching for a starting cornerback to put opposite Brent Grimes.

A second tight end — Dion Sims, Michael Egnew or rookies Arthur Lynch and Harold Hoskins — must be identified, and the Dolphins need to find someone to challenge Marcus Thigpen for his return specialist role.

And of course Tannehill and Miller need to continue to steadily improve.

But that's what training camp is for, and Miami's front office and coaching staff better make the necessary edits before releasing this production to the masses.
